Wednesday 20th October 2021: It's interesting to see that the TEP (Trans-Equatorial Propagation) openings are continuing on 144 MHz in South America.
This is a sample of the TEP spots from the DX-Cluster with distances in the region of 5300 to 6000kms... Spotter Freq. DX Time Info Country

It's nice to see that a lot of the reports for the opening were on SSB...
In the video, LW2DAF near Buenos Aires is working HI8DL in the Dominican Republic. Note the distortion due to TEP.

distortion is even worse.
This is actually a very good reminder to all of those stations who stay all
of the time on FT8 that they might be missing some good openings. If the
TEP signals are too distorted then FT8 doesn't work.
It's all about using the appropriate mode for the conditions at the time.
